UI low fps when opened #1986

Open Jalapan opened 1 year ago

Jalapan commented 1 year ago

when the main ui window is open the fps drops to 30fps and it stays untill mouse is moved outside of ui window or application is minimized

Do you have an Nvidia GPU with a high-refresh rate/ Gsync setup?

Jalapan commented 1 year ago

Yes 4090 and monitor running 140hz

Rem0o commented 1 year ago

I believe you can "exclude" a program in the Nvidia control panel from gsync/high refresh rate stuff. It's a common problem for WPF applications, and sadly there isn't any solution that I found yet except this workarround.

Hey, same problem here. The UI is terribly laggy, specially noticable when switching windows into FC. We're talking less than 15fps, mouse pointer is teleporting

Setting up GSYNC like this doesn't change anything unfortunatly :

@sh4rkman I believe its a "per app" setting you need to apply. https://i.imgur.com/vRbRDTz.png

Indeed ! Works like a charm.

I don't know WPF but isn't here something to do on your side, add a tickbox to disable GPU acceleration or something ? I'm pretty sure FC is used largely by gamers who love high refresh rates and led's :]

@sh4rkman the bug was reported in the WPF open source repo, and while tons of different devs piled in saying it's a widespread issue, nothing came out of it. If there was an easy fix, would have done it ages ago. WPF runs on DirectX directly, so it is natively GPU accelerated.
